I found a zip with all the templates here on RD, deleted already. It's the files on the Drive link. When I was searching for it, I tried to look for the 3d files to open in mudbox and create my own templates. If you really want that, prepare yourself for a really long trip hahahahaha.
Don't remember where, but I saw a tutorial that you need to download Unreal Engine, run the 3D files from ACC, export in a format that on Mudbox you can isolate just the parts that the livery is applied on, plan it, export in PNG and finally, you have your template
